Embodiment 1

[0030] figure 1 and image 3 Shown is a punching and cutting composite drilling tool provided by the present invention, including a drill bit 1 , an impact structure 2 , a transmission structure 3 and a hydraulic motor 4 . The drill bit 1 includes a percussion drill 1-1 and a PDC drill 1-2, the PDC drill 1-2 and the percussion drill 1-1 are arranged at intervals, and the percussion teeth 1-1.1 set on the percussion drill 1-1 are connected with the percussion drill 1-1. The drill bit body is brazed, which is convenient to replace the impact teeth 1-1.1 of different shapes according to different geological conditions; the impact drill bit 1-1 is connected to the impact structure 2, and the impact structure 2 includes a rotary part, a top extension part and an axial force transmission part, and the rotary part Connect the power unit. The rotary part includes a cam 2-2, the protruding part includes a roller 2-3 and a roller seat 2-4, the axial force transmission part is a transm...

Embodiment 2

[0034] The scope of protection of the present invention is not limited to the mechanism mentioned in Embodiment 1. When the rotary part in Embodiment 1 is an annular boss with smooth ends, and the protruding part is a cam roller and a roller seat, when the annular boss rotates , the friction drives the cam roller to roll, because the radius of the cam roller changes, it drives the axial movement of the roller seat, and the axial force is transmitted to the impact drill through the axial transmission part, and the axial impact movement of the impact drill can also be realized .

Abstract

The invention discloses a punching and cutting composite drilling tool, which relates to the field of drilling equipment and is mainly used to solve the problems of low working efficiency and high wear rate of the drill bit only relying on the rotation of the drill bit to break rocks. Its main structure includes a PDC drill bit and a percussion drill bit, and is characterized in that it also includes a percussion structure connected with the percussion drill bit. The punching and cutting composite drilling tool provided by the invention is suitable for various formations with different geological conditions, and has high construction efficiency and small wear of the drill bit.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a punching and cutting composite drilling tool. Background technique [0002] Drilling is the project of using mechanical equipment to drill the formation into cylindrical holes with a certain depth. Drilling is widely used in many fields such as oil and gas drilling engineering, mining, geological drilling, construction engineering, tunnel engineering, etc., either to obtain physical data buried underground, or to open channels, or to observe geological dynamics. play an indispensable role in development. [0003] The drill bit is a rock-breaking tool used in drilling engineering to break rock and form a wellbore. Conventional drill bits used in drilling engineering today mainly include three-cone drill bits, polycrystalline diamond compact drill bits (ie, PDC drill bits) and punching drill bits (also known as rotary punching bits or drill bits). [0004] The tri-cone bit ma...
